Do you have any tips for my flight to Trinity?
Wherever you're coming from, flying can be a pleasurable experience if you're prepared. Check out these handy tips that will get your Trinity holiday started on the right foot. What to pack in your hand luggage:

  • First things first, pack in your passport, travel documents, credit cards and vital medications. Next, you'll need some entertainment to while away the time. A juicy novel and a tablet crammed with your favourite movies are good options. If you intend to catch forty winks, a neck pillow and a pair of earplugs will also be useful. Finally, leave some space for a toothbrush and some cleansing wipes to ensure you touchdown looking fresh and raring to go.

Do not pack the following items in your hand luggage:

  • Check carefully that you don't have a pocket knife hiding in your carry-on luggage. Other banned items include explosive or flammable products, such as fuel and matches, and gels and liquids in containers larger than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • Your main priority is to be as comfortable as possible. Go for easy-to-remove footwear, dress in loose, breathable clothing and remember to take a sweater in case you get chilly in the cabin.
  • The result of sustained periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect passengers on long-haul flights. Reduce the risks by staying hydrated, keeping your ankles and legs moving and wearing compression tights or socks.

How to get through airport security fast when flying to Trinity?
As savvy travellers know, the secret is to be organised before you arrive at airport security. That way, you'll be hopping onto that plane to Trinity in the blink of an eye. Follow these helpful tips and get your trip off to a great start:

  • Keep your boarding pass and passport handy. They'll be the first things you'll be asked to show at airport security.
  • Your jacket, belt, keys and other small items, like your earphones, will be required to go through the X-ray machine. Make the whole process faster by removing them before your turn arrives.
  • For just a few minutes, you'll need to unplug from the digital world. Your tablet, phone and any other electronic devices will also need to go through the scanner.
  • Remember to remove gels and liquids from your carry-on bag. They often need to be sent through the X-ray scanner separately. Each item should be no larger than 3.4 ounces (100 millilitres) and everything must fit inside a single quart-size (one litre), clear zip-close bag.
  • Lightweight sneakers are a sensible footwear choice as you're less likely to be required to remove them when passing through security. Safety boots and other bulky shoes are often subjected to extra screening.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them in your checked luggage. They won't be allowed on board and will be confiscated.
